Remove unreachable intrinsic
This is now supported by the interpreter with https://github.com/rust-lang/rust/pull/74459 . We can remove this intrinsic implementation here.
This is covered by this test: https://github.com/rust-lang/miri/blob/master/tests/compile-fail/unreachable.rs
I guess we need to wait until the rust-lang/rust PR merges into nightly, and then we can update `rust-version` hash in the PR, right?

Auto merge of #1480 - RalfJung:diagnostic-stacktrace-fix, r=oli-obk
...
fix non-fatal diagnostics stacktraces
Our non-fatal diagnostics are printed *after* completing the step that triggered them, which means the span and stacktrace used for them is that of the *next* MIR statement being executed. That's quite bad, obviously, as pointing to where in the source something happens is their entire point.
Here's an example:
```rust
use std::ptr;
static mut PTR: *mut u8 = ptr::null_mut();
fn get_ptr() -> *const u8 { unsafe { PTR }}
fn cause_ub() { unsafe {
let _x = &*get_ptr();
} }
fn main() { unsafe {
let mut l = 0;
PTR = &mut l;
let r = &mut *PTR;
cause_ub();
let _x = *r;
} }
```
This example is UB; if you track the pointer tag that is given in the final error, it points to the entire body of `cause_ub` as a span, instead of the `&*get_ptr();`.
I am not sure what the best way is to fix this. The cleanest way would be to capture a stack trace before the step and use it in case of a diagnostic, but that seems silly perf-wise. So instead I went with reconstructing the old stacktrace by going back one step in the MIR. This is however not possible if we were executing a `Terminator`... I think those cannot cause diagnostics but still, this is not great.
Any ideas?
